The street where I live is undergoing a major pavement overhaul. The sidewalks fitted with new travertine marble, potholes filled, and the street grated, stripped, leveled and re-tarred. In this procedure, the old level was uncovered. I was surprised to see that under a thick blanket of gravel and asphalt, my street used to be paved in beautiful sanpietrini cobblestones. They have once again sadly been covered, though.
